Common Opposites – Antonyms
A word that has the exact opposite meaning of another word
is its antonym. Life is full of antonyms, from the "stop" and "go"
of a traffic signal to side-by-side restroom doors labeled "men"
and "women. Most antonyms are pretty obvious, like "good" and
"bad," or "black" and "white." Some words can be transformed
into their antonyms simply by adding the prefixes "un," "in," or
"non," as when "likable" is changed into its antonym, "unlikable."
